Best Ever Frosted Banana Bread Bars are my family’s all time favorite dessert! Hands down! No questions about it. If I could only make one dessert for the rest of our lives, this is the one they would pick! These seriously addicting, cream cheese smothered bars are sure to be a hit! The decadent cream cheese frosting will knock your socks off! You won’t believe how amazing they taste. Frosted Banana Bread Bars are an old-fashioned dessert jam packed with lots of banana flavor. This recipe makes enough to feed a crowd and is perfect for sharing at potlucks and family picnics. Just be sure to bring copies of the recipe! Everyone’s gonna want this one!!
Here’s all you’ll need: butter, sugar, eggs, sour cream, vanilla extract, flour, baking soda, salt, bananas, cream cheese, and confectioners sugar.
In a large bowl, cream 1/2 a cup of butter and sugar until light and fluffy. You can melt the butter if you don’t have time to soften. It won’t hurt the recipe one bit! I love watching people try Frosted Banana Bread Bars for the first time. The reactions are priceless!! I’m not kidding!
Next beat in the eggs, sour cream and vanilla until combined. The sour cream is the secret to keeping these beloved bars moist and delicious!! Mix in the baking soda and salt. Then gradually blend in the flour. When my hubby and I got married, we actually had people tell us to skip the wedding cake and just make Frosted Banana Bread Bars instead! Really!!
Now we need to mash our bananas. This is my favorite way to use ripe bananas, the riper the better! You could use a food processor or blender for this part, but what fun would that be?!? Plus it’s extra dish washing! Nope, not for me! So instead I just place the bananas in a ziploc baggie and squish away. I like to recruit my messiest baking helpers for this job. You know those slime loving kids! Nathan I’m looking at you kid! Make sure the bag is sealed up tight and let the kids squeeze and squish away. When you’re squishing’s complete, cut a hole in the corner of the bag and squeeze the contents into our batter. Blend until just combined.
Lightly grease a 13″X9″ pan with cooking spray. Pour our batter into the baking pan. Bake in a 350 degree preheated oven for 30-35 minutes or until a toothpick inserted in the middle comes out clean. Test as many times as you’d like! We’re going to smother those toothpick holes with cream cheese frosting!! Cool completely. The original recipe has the serving size listed as 48 servings. There is just no way!! I’ve seen guys take ’em out by the row. I won’t name names but you know who you are!!
While we’re waiting for the bars to cool, we can tackle that cream cheese frosting! This rich and creamy frosting seriously makes the whole recipe!! In a large bowl, beat together the cream cheese, butter and vanilla until light and fluffy. Don’t be afraid to nuke that butter and cream cheese for 30 seconds in the microwave. It’s WAY easier to mix when it’s softened. Gradually beat in the confectioners sugar one cup at a time until all four cups have been added. Now I hope your banana bars have cooled by now otherwise you’re putting yourself at risk to eat the whole bowl of frosting! Trust me, I’ve seen family members huddled around the bowl scooping this stuff out by the spoonful! This stuff is a hot commodity!!
Spread a thick layer of cream cheese frosting over top. Grab a fork, heck even just use your hands, and enjoy!! If you somehow end up with leftovers, first let me know how that happens to begin with?!? But also don’t forget to refrigerate! I’ve also heard of people adding nuts, but those people are kinda ridiculous!! Looking for more 13″X9″ pan recipes to try? Our Frosted Fudge Brownies are a chocolate lovers dream!

Thanks Emily! They are seriously addicting!
I am so going to make these! They look amazing and the perfect type of treat.
Make sure you get the first piece! They disappear quickly in our house!
This looks delicious. Although I would skip the sugar. I find banana sweet enough on its own.

That’s a version I’ve never tried! I’d be interested to know how they turn out.
I made banana bread like 3 times this week because there were some overripe bananas at the store for only 15 cents a pound! (Instead of the 45 cents a pound they normally are!) Next time i’ll Have to try it with your icing recipe!!!
